api调用实例python_django API 中接口的互相调用实例

我就废话不多说了,还是直接上代码吧!

url = "http://%s:%s/api-token-auth/" % (ip, port)

query_args = {

"username": username,

"password": password

}

resp = requests.post(url=url, data=query_args)

token = json.loads(resp.text)["token"]

headers = {"Authorization": "JWT" + " " + token} # 拿到token,拼成headers

post_url = "http://%s:%s/message/message-level-two/"% (ip, port)

data = {

"app": app,

"url": url,

"message_id": message_id,

"head": head,

"title": title,

"userprofile_id_list": userprofile_id_list

}

headers = self.headers

requests.post(url=post_url, data=data, headers=headers)

获取当前请求的ip和端口

host_ip, host_port = self.request.META.get("HTTP_HOST").split(':')[0], \

self.request.META.get("HTTP_HOST").split(':')[1]

常见的请求头如下:

CONTENT_LENGTH – The length of the request body (as a string).

CONTENT_TYPE – The MIME type of the request body.

HTTP_ACCEPT – Acceptable content types for the response.

HTTP_ACCEPT_ENCODING – Acceptable encodings for the response.

HTTP_ACCEPT_LANGUAGE – Acceptable languages for the response.

HTTP_HOST – The HTTP Host header sent by the client.

HTTP_REFERER – The referring page, if any.

HTTP_USER_AGENT – The client's user-agent string.

QUERY_STRING – The query string, as a single (unparsed) string.

REMOTE_ADDR – The IP address of the client.

REMOTE_HOST – The hostname of the client.

REMOTE_USER – The user authenticated by the Web server, if any.

REQUEST_METHOD – A string such as "GET" or "POST".

SERVER_NAME – The hostname of the server.

SERVER_PORT – The port of the server (as a string).

获取请求头内容的用META

示例:

def index(request):

ip = request.META.get("REMOTE_ADDR")

return HttpResponse("你的ip地址是%s"%ip)

http://10.254.30.27/1

self.kwargs[‘pk'] # 可以拿到后边的 1

补充知识:django 使用requests请求相关接口

1、如果是get请求接口,并且需要带相关参数的话,可以借鉴下面的代码:

import requests

from django.http import JsonResponse

def get_info(request):

url = 'http://www.baidu.com'

params = {'id': 1, 'user': 'lin'}

response = requests.get(url=url, params=params)

return JsonResponse(response.text, safe=False)

这样将会返回一串json的字符串数据。

2、如果是post请求接口,并且需要带相关参数的话,可以借鉴下面的代码:

import requests

from json import dumps

from django.http import JsonResponse

def get_info(request):

url = 'http://www.baidu.com'

data = {'id': 1, 'user': 'lin'}

response = requests.post(url=url, data=dumps(data))

return JsonResponse(response.text, safe=False)

注:

(1)、其中必须注意的为data这个参数,必须要用dumps(data)转换一下,不然会报错,response状态码为400,bad request error 400 while using python requests.post function。

(2)、如果需要在post请求底下加相关请求头的话,可以借鉴下面的代码:

import requests

from json import dumps

from django.http import JsonResponse

def get_info(request):

url = 'http://www.baidu.com'

data = {'id': 1, 'user': 'lin'}

headers = {'content-Type': 'application/json', 'Accept': '*/*'}

response = requests.post(url=url, data=dumps(data), headers=headers)

return JsonResponse(response.text, safe=False)

这里如果response的状态码报415错误的话,即HTTP请求415错误 – 不支持的媒体类型(Unsupported media type),这就是content-Type可能写错了,就要注意一下了,因为通常接口会封装一些参数到请求头底下。
